Beta-Decay Properties of Neutron-Rich pf-shell Nuclei

Determining weak interaction rates of pf-shell nuclei is necessary to model late stage supernova evolution. As all rates cannot be measured, we must develop and test model calculations. We present shell model calculations of $\beta $-decay half-lives and Q-values for $^{\mathrm{47-60}}$Ca, $^{\mathrm{46-57}}$Sc and $^{\mathrm{51-62}}$Ti isotopes. These calculations, performed with NuShellX using three different interaction Hamiltonians, are compared to experimental measurements where possible.
